16F877A Correct set up for port a

[enigma]

Hi Dave

I think its still cmcon = 7 which I`m sure is wrong, I`ll try ACCON1 = 1 and see. Its certainly that because the setup works if I apply the serial to portb and recode.


Cheers Pete

Do you have
ADCON1 = 7
someplace in your code. ( I think that is correct for your chip, might be ANSEL )

Hi Dave

Thanks ADCON1 did it, I had a feeling it was coming up in Analog mode I just couldnt find the correct register to set.

Many thanks, Pete
